Abstract: In this study, conservation agriculture-based tillage (CA-T) practices (zero tillage, minimum tillage and strip tillage) in rice-maize production systems were implemented through on-farm participatory research trials for five years in Bangladesh to evaluate them under farmers’ field conditions, build awareness among farmers about such practices, and diffuse them in the farming communities. This study examines the adoption of those practices using farm level data from participating and non-participating farmers from and surrounding the field trial areas. For this, a farm household survey was conducted with 606 farmers, who earlier either participated or didn’t participate in the trials. A double hurdle model was employed to determine the factors influencing CA-T adoption and intensity of its adoption. During five years of the trial period, participatory and non-participatory farmers respectively adopted CA-Ts in 12% and 3% of annual cropped areas with overall adoption of 6.6%. Several factors contributed to the probability and intensity of adoption. Variations in adoption existed between locations, cropping systems, and seasons. Contrary to conventional wisdom, the propensity score matching analysis showed that yields either remained unchanged or were higher in the CA-T practices compared to farmers’ practices. Access to critical inputs, knowledge dissemination, capacity building and cropping season influenced the diffusion of CA-T practices.
